Abrégé

The present invention relates to a method comprising a selective hydrogenation step of vegetable oil derivatives that are mixed with light olefins and conveyed to the metathesis section, wherein the renewable carbon content of the olefins and aviation biokeresone depends on the type of origin of the light olefin stream. After metathesis, the reactor effluent is conveyed to the separation and purification section, in which a 1-decene stream (99% m/m), a C11-C14 olefin stream (99% m/m) and a methyl ester or C10-C14 carboxylic acid stream are obtained and conveyed for coprocessing together with aviation kerosene of fossil origin in an existing hydroprocessing unit. An excess of light olefins is admitted at the input, and the unreacted portion is separated and returned to the metathesis section. A small amount of compounds of higher molecular weight is also formed, as as result of autometathesis reactions, which is separated and incinerated or used as fuel for furnaces or boilers to generate energy. The saturated FAME stream (stearate, palmitate and methyl) in the load can be used for coprocessing (up to acceptable levels) or commercialised in the form of biodiesel.

The present invention is a system for treating effluent from robotic equipment used to remove marine biofouling, primarily targeting organisms such as orange cup coral, which collect on hulls of floating units for transporting oil and derivatives thereof, or on production and exploration platforms. The system involves separating the flow into two elemental phases: solid and liquid. In the solid-phase flow, treatment is carried out in steps essentially comprising particle-size reduction, direct oxidation, oxidation residence, separation, drying, temporary hermetic storage, packaging, and automatic transportation for final storage. The liquid phase includes a step of centrifuging, adsorption, inerting, and discharge of treated effluent into the sea in accordance with environmental law. The entire system is automated to minimize manual actions and interventions, and is programmed to run without interruption as a function of the flow rate of raw effluent.

The present invention relates to a synthetic-silica catalyst used in a heterogeneous catalysis method for the effective conversion of residual glycerin resulting from the production of biodiesel into formic acid with high selectivity and stability, in a continuous-flow reaction. It should be noted that products with high added value are formed with the mere presence of an oxidizing agent, including without a catalyst. In this case, the conversion of the residual glycerin occurs by homogeneous catalysis, by the action of the components left over from the synthesis of the biodiesel, with the formation of major components, such as formic acid, cyclic ethers and diglycerol, in continuous-flow and reflux reactions. The reaction can also be brought about by adding sodium salts to the process of homogeneous catalytic conversion of the commercial glycerin. The process developed in the present invention reuses the residual glycerin without the need for purification before its transformation into products of high added value and renewable origin, enhancing the usefulness and potential of the invention.

The present invention relates to a thermal insulation blanket for undersea lines designed to help keep temperatures above the desired minimum in the related projects, since the fluids transported therein tend to lose heat to the environment. The invention resolves problems such as the formation of paraffins or incrustations, increased viscosity of the oil and hydrate formation, inter alia. The invention should be used at greater depths (where the external temperature is lower) and near to the fluid source, where the fluid temperature is greatest, and where the potential heat exchange is most intense on account of the greater temperature difference. The blanket then keeps the water heated by the line in the vicinity of the line, providing additional insulation. Additionally, the blanket is installed longitudinally on the related lines by unrolling (to facilitate installation).

The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of a bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high-molecular-weight linear paraffins (up to 40 carbon atoms).

The present invention relates to a process for producing aromatic compounds from streams containing straight chains of 5-18 carbon atoms of fossil or renewable origin and use within the field of catalytic cracking aiming for regenerator operation at a much lower temperature of between 480ºC and 620ºC, preferably at a temperature of between 500ºC and 600ºC. The coked catalyst generated by cracking light streams with low delta coke generation potential can be subjected to combustion at a lower temperature. The regeneration temperature should be at least 40°C and no more than 100°C higher than the reaction temperature, maintaining high catalyst circulation to maintain the energy balance in the reaction zone. The minimum regeneration temperature can be ensured by installing a furnace for preheating air before it enters the regenerator and passes through the air distributor inside the regenerator. The catalyst used should contain zeolite with pores of intermediate size. Such conditions significantly favour the production of aromatics and the octane rating of the naphtha produced.

The invention uses the principle of the pneumatic turbine and a cooling system for the entire welding torch, in which the gas used in the welding process, or even the compressed air, enters through a conduit in the axial direction to the consumable, thus moving a turbine, which in turn moves a nozzle and a nozzle holder. The welding torch can be used for extended periods of time at 100% duty cycle, in NEMA class I welding machines, since it is water-cooled. In addition, the torch can be used on any welding source made by any manufacturer, whether the machine is new or very old, since the euro standard (adopted) is the same. This means that there is no need to acquire a new welding machine, but simply a torch. In construction and assembly environments, such as welding risers, refineries, joint welding, cladding, and processes aimed at constructing a part using just one welding consumable, the use of said torch will provide significant savings in terms of reduced time and cost. This torch can also be used on any existing welding device, within the aforementioned processes.

The invention discloses a system and a method for reducing pressure and drainage in the annulus of submerged flexible lines, for use in all flexible line structures and in any industry that uses these types of lines. The objective is to remove condensed water and to reduce partial CO2 pressure in order to restore the physical integrity of the lines. In addition to this, reducing gas pressure in the annulus enables line collection operations to be carried out more quickly, i.e. in less time. Relieving the pressure in the annulus also reduces the risk of the outer layer rupturing during operation, thereby reducing the risk of operator exposure to harmful gases when the line reaches the deck of the PLSV ship.

The present invention relates to a device and respective process for distribution of mixed charges comprising a flat tray in the form of a disc drained by a series of drainage tubes located above the surface of fixed beds of catalysts, capable of promoting the homogenisation and distribution of charges by means of said device. Such drainage tubes mounted in said manner have the objective of restricting and reorienting the flow of mixed charges, multiplying the points whereon they fall, principally of the liquid phase, onto said beds of catalysts. For the purpose of doing so said drainage ducts, being segments of tubes, distributed on the entire surface of said tray possess caps affixed at the upper extremity thereof impeding the direct flow of charge onto the bed of catalyst, creating a reservoir of liquid on the tray, subsequently being drained down such device in a more controlled manner.

The present invention comprises a thermocatalytic cracking process for the production of diesel oil from a charge of vegetable origin made from seeds of oleaginous plants in refineries possessing at least two FCC reactors. At least one of such reactors processes heavy gas oil or residue under conventional conditions whilst at least one of such reactors processes the charge of vegetable origin made from seeds of oleaginous plants under conditions suitable for production of diesel oil. Said process employs the same catalyst utilised in the fluid catalytic cracking process which, simultaneously, processes a conventional charge. The diesel, or biodiesel, oil produced by means of said process is of superior quality having a cetane number exceeding 40 given that the cracking reactions occur at low temperatures and the products obtained are less oxidised and consequently purer than products obtained by means of existing technology.

A method to exploit the glycerin obtained as a by-product of the industrial process to produce biodiesel inside or out of the industrial production unit, providing a reduction in the environmental liability that may be caused by an excess in the production of glycerin that cannot be exploited for industrial use. The referenced method uses recycling of the glycerin obtained through industrial process to produce biodiesel, using a process basically consisting of four stages: a) Captation of the glycerin produced as a by--product of the industrial process for producing biodiesel; b) hydrogenation of said n-propanol glycerin, c) recycling of the n-propanol thus obtained to be added to a mixture of alcohols; and d) transesterfication of the n-propanol mixture added to the alcohol mixture, together with raw material triglycerides from renewable resources in order to obtain biodiesel. The referenced recycling of the n-propanol stream provides a reduction in the amount of the alcohol mixture necessary for the industrial process to produce biodiesel, consequently reducing operational costs.
